MDAnalysisData is a collection of datasets from the field of
computational biophysics, with an emphasis on trajectories from
molecular dynamics (MD) simulations and the structure and dynamics of
biomolecules.

Data sets are stored at external stable URLs (e.g., on figshare ,
zenodo, or DataDryad) and not inside the MDAnalysisData
package. Instead, the MDAnalysisData.datasets provides a simple
interface to download, cache, and access these externally hosted data
sets.

The files can be easily used with MDAnalysis but the package is
standalone and can be used for any purpose, for instance, to
provide examples for workshops and classes, and, of course, to try out
other tools for analyzing simulations.
